Answer:

Step-by-step explanation:
x^2-24x+144=0
When you see it as =0, that doesn't mean it's 0. it means it needs more deep solving.
x^2+24x+144-144=0-144
x^2+24x=-144
x^2+24x+12^2=-144+12^2
x^2+24x+12^2=0
(x+12)^2=0
x+12=0
x=-12
Answer:
x = 12
Step-by-step explanation:
Step 1: Write quadratic
x² - 24x + 144 = 0
Step 2: Factor
(x - 12)(x - 12) = 0
Step 3: Find roots
x - 12 = 0
x = 12
